    摘要： A cylinder head for an engine having a two-plane water jacket in which a lower chamber at one plane through the head cools the fire deck of each cylinder and a cross-flow passage for the coolant is spaced above the lower chambers in a second plane through the head directs coolant to an outlet. The two planes of the water jacket are connected by an annular passage surrounding the injector nozzle sleeve and has machined surfaces whereby the size of the flow channel and thus the coolant flow between the two planes is better controlled to enable more even cooling of the fire deck resulting in less variability in fire deck temperature from one cylinder to one another. The lower chambers cooling the fire deck are separate for each cylinder to prevent heated coolant from one cylinder flowing to the next cylinder fire deck.

    摘要翻译： 一种用于具有双平面水套的发动机的气缸盖，其中通过头部的一个平面处的下腔室冷却每个气缸的消防甲板，并且用于冷却剂的横流通道在第二平面中的下腔室之间间隔开 通过头部将冷却液引导到出口。 水套的两个平面通过围绕注射器喷嘴套筒的环形通道连接，并且具有加工表面，由此更好地控制流动通道的尺寸，从而更好地控制两个平面之间的冷却剂流动，以使得能够更均匀地冷却防火甲板 导致防火甲板温度从一个气缸到另一个气缸的变化较小。 冷却消防甲板的下室对于每个气缸是分开的，以防止来自一个气缸的加热的冷却剂流到下一个气缸消防甲板。

    摘要： A center-closed power steering system provides power steering assistance in engine-off conditions for reduced fuel consumption. The power steering system includes a hydraulic pump mechanically driven by the engine, a high pressure accumulator, a steering gearbox fluidly connected to the accumulator, and a center closed valve mechanically connected to a driver-operated steering wheel. The valve is configured to selectively control flow of pressurized fluid from the accumulator to the steering gearbox to provide power steering assistance. The inner shaft of the rotary center-closed valve is provided with a cavity with V-shaped notches on the transition surfaces on lands configured to sealingly engage the inner surface of the valve outer sleeve, in order to provide a smooth transition in flow for power steering assistance, and a better driver feel.

    摘要： A flex fuel internal combustion engine system includes means for sensing ethanol concentration of the fuel. If the ethanol concentration is determined to be above a given threshold, engine operation is adjusted for lean combustion of the fuel. An aftertreatment system is provided to remove harmful emissions from the exhaust.

    摘要： In an internal combustion engine adapted to combust alcohol blend fuels (i.e., fuels containing greater than 20% alcohol by volume), a dilute combustion mixture (e.g., with substantial EGR), intake air cooling, and latent cooling caused by vaporization of the alcohol fuel, are used together with a compact combustion chamber (in which the distance between the spark plug tip and furthest point of the combustion chamber is less than one-half the cylinder bore diameter) and controlled spark retardation to enable the use of a high compression ratio (greater than 15:1), for improved efficiency without triggering auto-ignition. Thermal brake efficiency significantly exceeds that for conventional gasoline engines, thereby improving the potential cost-effectiveness of alcohol fuels. Stoichiometric operation is used for optimal emissions control.
